Abstract
A new procedure is presented for determining dynamic characteristics and seismic response of adjacent buildings linked by active tendon devices. Dynamic characteristics of active tendon-linked adjacent buildings are obtained by a generalized modal analysis approach. Random seismic response of adjacent buildings linked by active tendon devices is determined by a combination of the generalized modal analysis approach and a pseudo-excitation method. Based on the derived formula, a computer program is written and extensive parametric studies are performed to assess the effectiveness of active tendon devices and to identify optimal type of sensor and beneficial parameters of devices. It is showed that using active tendon devices of proper sensors and parameters to link adjacent buildings can increase the modal damping ratios and reduce the seismic response of both buildings significantly.
